Slurry dewatering and curing construction process

Abstract

The invention provides a slurry dewatering and curing construction process. The process flow is as below: S10, installing the overall equipment in place, and preparing a coagulant mucilage and a dewatering agent; S11, calculating the addition amount of coagulant mucilage per minute by a control system according to the slurry flow and addition rate of the coagulant mucilage, controlling the rotating speed of a controllable screw pump in accordance with the addition amount of coagulant mucilage per minute, and adding the coagulant mucilage into the slurry; and S12, calculating the addition amount of the dewatering agent per minute by the control system according to the concentration and flow of slurry mixed with the coagulant mucilage, controlling the rotating speed of a controllable dosing pump according to the addition amount of the dewatering agent per minute, adding the dewatering agent into the slurry mixed with the coagulant mucilage, and flowing the slurry into a second pipeline mixer of a slurry dewatering and curing system for dewatering and curing treatment. The slurry dewatering and curing construction process provided by the invention can realize rapid dewatering and curing treatment of slurry, reduces the workload of construction, and shortens the construction period.

Description

technical field [0001] The application relates to the field of environmental protection solid waste treatment, in particular to a construction process for dehydrating and solidifying mud. Background technique [0002] With the rapid development of the national economy in my country's coastal areas, the demand for living construction land has increased sharply, resulting in the continuous expansion of the reclamation area, and the demand for sand and soil materials in reclamation projects is also increasing. However, sand and soil resources are increasingly scarce in dredger filling construction. However, there is a large amount of tidal flat mud outside the enclosure, which not only endangers the marine ecological environment, but also poses safety hazards to the reclamation project. At the same time, the dredging mud in the dredging project of river and waterway cannot be effectively solved. Most of the dredging mud is disposed of by discarding landfills or low-lying areas...
